I've done some straight CO2 and it isn't a ton different. If you look at the Miller weld calculator, you have to increase your voltage some to get a similar weld profile/strength. For someone who is doing stuff in their garage, I honestly would reccomend it. As Steve said-cheaper, and you don't necessarily have to get bottles filled at a welders supply store. Have a store that sells and fills paintball gear you can go there.

A student now but really want to weld everyday. Want to learn everything about everything. Want to become a knower of all and master of none. Instagram: @farmweldingNick
